Attached is a script I developed in 2010 which will look at the GPIOs.

I looked through my email archives and the problem appears to be
different to what I recalled. It seems the problem is that not all
QNAP devices have a fan; if you enable the fan on those devices,
you'll get period error messages in the log file saying that it cannot
read the status of the fan. Anyway, there are very few devices
without a fan. I believe only the TS-109 and TS-119. It should be
possible to detect these via GPIOs.
